Hi,

I cannot start Linux PV guests. "sudo xl create -c" reports that a domain has successfully started but "ps -ef | grep qemu" returns no output and "sudo xl list" doesn't show that the PV domain has started.

Please review the following installation steps which I have written and see if there are any mistakes.

XL Domain Configuration File for Fedora 16 x86_64 PV domU (Incomplete Configuration, Not Tested, Do Not Use)


You will need to install apache2 and create a local http mirror.


sudo apt-get install apache2


cd /media

sudo mkdir fedora

cd ~/Downloads

sudo mount -o loop Fedora-16-x86_64-DVD.iso /media/fedora

cd

mkdir -p vms/f16

cd /media/fedora/images/pxeboot

cp vmlinuz initrd.img ~/vms/f16/


sudo nano /etc/xen/Fedora16x86_64


# Kernel image to boot


kernel = "/home/teo-en-ming/vms/f16/vmlinuz"




# Ramdisk (optional)


ramdisk = "/home/teo-en-ming/vms/f16/initrd.img"



#bootloader="/usr/bin/pygrub"


cd /etc/xen/images/

sudo dd if=/dev/zero of=fedora16x86_64.img bs=1024k seek=10000 count=0


To install Fedora 16 x86_64 as a paravirtualized guest domain,


sudo xl create -c Fedora16x86_64


After installing Fedora 16 x86_64 PV domU,


sudo nano /etc/xen/Fedora16x86_64


# Kernel image to boot


#kernel = "/home/teo-en-ming/vms/f16/vmlinuz"




# Ramdisk (optional)


#ramdisk = "/home/teo-en-ming/vms/f16/initrd.img"



bootloader="/usr/bin/pygrub"


# XL domain configuration file for Fedora 16 x86_64 PV domU

# Please refer to "man xl.cfg" for further explanations.

name="Fedora16x86_64"


builder="generic"


vcpus=2


memory=1024


on_poweroff="destroy"

on_reboot="restart"

on_crash="destroy"


disk=[ 'format=raw, vdev=hda, access=rw, target=/etc/xen/images/fedora16x86_64.img' ]


vif=[ 'bridge=virbr0' ]


vfb=[ 'vnc=1,vnclisten=localhost,vncdisplay=2,vncunused=1,vncpasswd=,sdl=0' ]


gfx_passthru=0


# Step 1

# To install Fedora 16 x86_64 PV domU, configure the kernel, ramdisk, and extra keys below and comment out bootloader.

# Kernel image to boot

kernel = "/home/teo-en-ming/vms/f16/vmlinuz"


# Ramdisk (optional)

ramdisk = "/home/teo-en-ming/vms/f16/initrd.img"


# Kernel command line options

#extra = "root=/dev/xvda1"


# Step 2

# To boot the already installed Fedora 16 x86_64 PV domU, comment out the keys in Step 1 and uncomment bootloader below.


#bootloader="/usr/bin/pygrub"

Please advise.

Thank you very much.

Yours sincerely,

Teo En Ming (Zhang Enming)
